This atlas of functional ultrastructure provides a detailed insight into the complex structure and organization of cells and tissues, highlights specific cellular and tissue functions, and the dynamics of diverse intracellular processes. Highly informative electron micrographs are complemented by explanatory texts, selected references and schemes. The concept that subcellular organelles provide the structural foundation for fundamental processes of living organisms is emphasized. The first part covers the cellular organelles and changes due to experiments or occurring under pathological conditions. The second part illustrates by selected examples principles of functional tissue organization and typical changes resulting from experimental induction or pathological situations. The second, revised and extended edition of the atlas, which includes a CD, thus provides an invaluable source of information for scientists and students of Medicine and Biological Sciences, particularly of Histology, Cell and Molecular Biology. Moreover, it will serve as a handy reference guide for diagnostic and research electron microscopy laboratories in clinical, industrial, and academic settings
